DESCRIPTION:Franziska Jahnke joins us for the logic seminar.\n\n\n\nAbstr
act: (Joint work with Sylvy Anscombe) In this talk we characterize NIP h
enselian valued fields modulo the theory of their residue\nfield. In par
ticular\, we show that every NIP henselian valued field satisfies some i
nstance of the Ax-Kochen/Ersov principle. We then\ndiscuss several conse
quences of the theorem\, including a characterization of all NIP fields
when one assumes the conjecture that every\ninfinite NIP field is either
separably closed\, real closed or admits a henselian valuation. We also
discuss open questions arising from\nthese results.
